| Summary: | In this study, researchers looked into how coating MBRs with polymethyl methacrylate (PMMA) affected their performance as a carbon dioxide gas sensor. Using a "soften-and-compress" technique, SMF28 produced the MBR shape, which was then coated in a PMMA solution to provide the three different conditions of single, double, and cascade. All forms of MBRs, even the most advanced cascade MBR-PMMA with a Q-factor of 7.47 x 105, were distinguished by the presence of microfibre. Sensitivity, linearity, stability, and repeatability of a carbon dioxide gas sensor were evaluated using MBR-PMMAs. Between 10% and 60% of carbon dioxide gas was consumed. Transmitted power analysis and wavelength shifting analysis were then compared to see which provided more accurate results. The results for Cascade MBR-PMMA were outstanding in every category. Here, the MBR with PMMA coating is arranged in a cascade, which may have an effect on the WGMs and therefore increase the MBR's adsorption capabilities as a sensor. |
